In this manner, all of the shift registers SRi are connected in series. Also, the output terminal OUT in respective light emitting cell array segment is connected to the input (in) of the drive circuit DSi.
- the input terminal IN of the first stage shift register SRi is connected to a data output of an image memory 3 of a central control unit 2. Also, the overall data transmission system operates in synchronism with a clock from a timing clock generator circuit 4 in the central control unit 2.
- bit map type image data of character strings are preliminarily stored in the image memory 3, in which each individual character is constituted of 16 ⁇ 16 dots.
- each 16 dot data corresponding to each light emitting cell array fraction will be hereinafter referred to as column data.
- Respective of the column data are represented by D1, D2, D3, . . . in order, and are generally referred to as Di.
- the central control unit 2 reads out respective column data in series from the image memory 3 and input to respective shift register string SRi connected in series sequentially.
- Each shift register SRi serves as a delay circuit of 80 bits (16 ⁇ 5 bits) so that each column data is input to the corresponding drive circuit DSi with a delay in the extent of 5 columns of the column data Dj from inputting to the input terminal IN.
- the timing clock generator circuit 4 reads out 16 bits of the column data from the image memory 3 and simultaneously supplies a latch signal for all of the drive circuits DSi.
- each column data of the image data are supplied to respective drive circuits in each light emitting cell array segment in order so that 16 in number of the LEDs 1 in the light emitting cells array segment are driven for display according to the 16 bits column data latched in the drive circuit.

- 16 ⁇ 16 dot light emitting cell array In contrast, in the shown embodiment, only three columns out of the sixteen columns of light emitting cell arrange segments are active. Therefore, at a moment, only fractions of the character image, which cannot be recognized as intended character image, can be visible. However, when the character image is scrolled at a speed higher than or equal to a predetermined scroll speed, the character image can be clearly recognized. In this case, the character image recognized is substantially comparable with the character image displayed on the 16 ⁇ 16 dot light emitting cell array.

- the column counter C is incremented by 1 to shift identification of the light emitting cell array segment Ai+1 to be made active for displaying.
- the value of the column counter C is checked if the column counter value C reaches the predetermined final value n, or not. If the column counter value C does not reach the predetermined final value n, the process is returned to the step 604 to repeat the foregoing process from the step 604. On the other hand, if the value reaches the predetermined final value, it represents that the column counter value C becomes equal to the predetermined final value n. In such case, the process is jumped to a step 608 to generate the latch signal.
- the start pointer P is incremented by 1 to advance the image to be displayed in the scroll direction by one unit.
